Enhancements for Error Handling and Regex Operation Optimization in Distributed Tensor Loading

[Madhav-MKNC]

Description

The tensor loading process, specifically within ThreadPoolExecutor and regex operations in get_load_path_str, requires enhancements to improve error handling and efficiency.

Enhanced Error Handling in ThreadPoolExecutor:

Current behavior lacks detailed error information when futures fail, making debugging difficult. Suggested enhancement involves catching exceptions within futures to log detailed failure information, including the specific tensor that failed to load.

Regex Operation Optimization:

The repeated use of regex in get_load_path_str for renaming and exclusion is computationally expensive. Proposed improvement involves introducing caching for regex operation results to avoid unnecessary recomputation, thereby improving performance.

These enhancements are critical for maintaining robust and efficient tensor loading in distributed computing environments.
